- Qt Undefined Reference To Signal
Qt undefined reference to 问题. 我用的是QT Designer,一般只有用到信号signals和槽slots时才会用到MOC,因为采用信号signals和槽slots. The connection mechanism uses a vector indexed by signals. But all the slots waste space in the vector and there are usually more slots than signals in an object. So from Qt 4.6, a new internal signal index which only includes the signal index is used. While developing with Qt, you only need to know about the absolute method index.

Apart from whatever is mentioned in this answer, also make sure to run qmake. i.e.:

That should fix these errors.
I have a class server for which I have created a signal joined(QString name). I call it in a function called join(QString name), however I'm getting the error
Server.o: In function Server::join(QString)': Server.cpp:(.text+0x48): undefined reference to Server::joined(QString)' collect2: ld returned 1 exit status
This is what my header file looks like:
Qt Undefined Reference To Signal
and this is my cpp file:
At the beginning of your class declaration you should have the macro Q_OBJECT and be sure to inherit from some QObject descendant.
